CONFIGURING LOOPBACKS

Loopbacks provide a way to test the data communication path between the Campus unit, the remote unit, and the remote host equipment. Depending on the remote unit, the Campus system supports the following types of loopbacks:

If both the local and remote units have a Campus-REX RS Interface Card, no loopbacks are supported.

•The Local to Local loopback tests the local data port and a small portion of the Campus-REX RS Interface Card.

•The Local HDSL loopback tests the local data port and the entire data path of the local Campus-REX RS Interface Card, including the local HDSL transceiver. The data path in this loopback extends to the HDSL line transformer, and causes the HDSL link to go down (a Link Alarm occurs).

•The Remote to Local loopback tests the local data port, the entire data path inside the local Campus unit, the HDSL line, the HDSL transceivers of both units, and most of the internal data path inside the remote unit.
